AI Technical Summary

Benefits of technology

The patent describes a protective product that includes an expanded slit paper sheet and an embossed paper sheet fixed to the expanded slit paper sheet along a portion of its length. The embossed paper sheet has bulged outwardly from the expanded slit paper sheet and helps to limit friction applied to an item that is inserted into a pouch of the envelope. The plurality of embossings also inhibits the wrinkling of the embossed paper and provides cushioning to protect the item within the pouch. The use of the expanded slit sheet material and the indented Kraft sheet as the outer material provides a lightweight very protective alternative that eliminates the need for plastics or heavier weight paper alternatives.

Problems solved by technology

The paper alternatives are costlier to manufacture and cost more for the end user to ship due to its increased weight as compared to plastic.

Abstract

A protective product, such as, e.g., an envelope or pouch, is provided that includes at least one expanded slit paper sheet in an expanded state, and an embossed paper sheet facing the expanded slit paper sheet and fixed to the expanded slit paper sheet along at least a portion of a length in an expansion direction of the expanded slit sheet paper. In the preferred embodiments, the embossed paper sheet has a plurality of embossings that increase the rigidity of the embossed paper sheet, thereby inhibiting deformation of the embossed paper sheet that is fixed to the expanded slit sheet paper.
